I did my hitch at the normal straight up position on the B&W, since the default positioning of the puck holes and gooseneck is adjusted to the rear by around 2 inches.  

 

That being said I just measured from center of jaws to inside of bed and then added the distance to the cab itself.  Jaws to inside of front of bed is 41 inches, add in distance to cab and your looking at around 44.5 to 45 inches due to the way the aerodynamic piece is on top of cab.  I guarantee I could "hit" my cab with my fifth wheel, but that would be a very tight turn and is usually never needed to turn that tight.  Previously I used a manual sliding Reese 20K hitch, had that hitch for the last 5 years and never once did I use the sliding feature.  

Please look at and confirm or correct  me. But looking at my 2020 oem puck configuration I can see the gooseneck ball placement is the 2 inches back but using the pucks placed my center of B&W puck non slider two inches ahead of it. I don’t believe they moved the pucks back like the ball. I will probably set my hitch in the back position but in normal position it is in front of ball.

The entire assembly was moved, so fifth wheel pucks and gooseneck were moved back slightly. My B&W center sits behind the axle and its in the straight up position.

Had a chance to use my Reese Goose Box on my 5er this weekend. Worked great with the factory puck system and I seemed to have a good clearance when turning or making maneuvers. Didn't push it to the limits in the turning area, but was close enough to do what I needed. I have the Reese 16k Goosebox and it performed well with my 14.5k 5er.

I am about to order my 2020 Standard box truck (moving from a LBZ with an 8' box), and I was wondering if you could measure from the center of the jaws where the king pin sits to the cab of the truck? I think this would help many of us greatly with our respective setups to verify a slider is not required.

Back window to ball center on my PullRite SuperLite is 47.25", which is about 2" ahead of the gooseneck ball hole.

Obviously I decided to not use a slider.

Im not necessarily concerned with where the pucks are in relation to the gooseneck, im concerned where the hitch is in relation to the axle.  In the straight up position at least on the B&W companion RVK3710 model, the hitch point is slightly rear of the axle.  Attached photos to sorta show, its very minimal probably less than 1.5 inches.

The kingpin mounts are relatively the same as before, the goose neck mount is 2" behind where it was in previous gen trucks. This was said to be due to the added bed length and also provided a better tow experience, since it is still centered over the bed. Someone stated it was designed this way as to spread evenly over the leafspings and axles for better weight distribution.

Has anyone found a sliding hitch to fit into the GMC 2020HD? I have a Pullrite superslide in my current 2015 2500HD and am getting the 2020HD this week. I did see that Pullrite show a new superslide for the 2020 HD as "coming soon". Anyone know the release date?

I don't think there has been a factory prep slider released yet. Just took delivery of my truck tonight and anxious to get my b&w non sliding hitch on the truck to measure if I have clearance.

Your better off just getting a rail adapter plate and using an older rail style hitch, essentially the samething but works with factory prep.

 

Something like this ….

Just an FYI... that particular rail adapter works with the 2019 and earlier configurations, not the new 2020 layout.

I chose not to go the Demco 6333 route as I was unsure if I would be able to adjust my pinbox height to compensate for the additional height from the rail adapter. I can only go up one more and my new truck is already taller. Not sure if that is a valid concern, but that was one decision point to try the B&W non-sliding.

Yes I knew that, was just stating that there are adapters out there for use with any hitch.

Generally speaking those adapters don't add any height over a normal rail kit install.  Pretty sure the ideal clearance is around 6 inches minimum, and the 2020 bed heights didn't change much.

      The not as clean as one would assume theme with the new engine oil, that reminds me of comments over the years with mechanics not always being so on board with filling an oil filter, not from the center anyway due to that typically being the clean side of the filter, danger of some contaminant falling into the filter if not careful but the realization now that the oil may not be as pure as one had assumed it would surely be. Yes it would be possible to fill from the small holes but that means messing with something to prop open the anti drain back valve if the filter is so equipped and not damage that valve in the process. Me, I have hardly ever prefilled an engine oil filter however I have prefilled diesel fuel filters with a filter on a fuel bulk tank and for anyone that has messed with diesel engines with filters and units that have a limited or no way of priming them, putting on a dry filter is a bad day to say the least with those crappy systems. But anyway back to not so clean engine oil, indeed perhaps its not so bad after all that I have not made a practice of prefilling oil filters.    As Grumpy Bear commented on keeping things clean, that I really have to wonder what the typical practice is at a dealer or any other shop that changes engine oil, do they make sure to wipe or wash off the oil plug and certainly if it fell into some gunk or onto a dirty floor, or that they wiped the filter mounting flange and didn't go and use some dirty rag and end up adding dirt to the inside of the head of the filter mount. Or be careless in how they stored or handled the new filter and if they were bumping into items under the vehicle with the filter opening facing up and having dirt drop right into the filter and if so right into the threaded center that is on the clean side. The top side, did they clean away the built up gunk that may be around the filler before removing the cap or to be really careful at that point that something right close to the filler hole that was hidden under the caps flange won't fall into the engine. Or did they clean the funnel or was that just laying there covered in oil from the oil change before and dust kicked up from sweeping the floor stuck to the oil and now that will go running into the next persons engine due to just not cleaning the funnel as "they won't know anyway" attitude as that young guy is more worried about taking a break so he can go outside and smoke a joint. Just random points that came to mind when I think about what some hired personnel may do that the shop foreman has no idea of or perhaps the whole attitude of some shops may be "eh ... who cares, they will never know the difference anyway".

      On the subject of OLM, Gm's OLM tool may be more "informed" than others brands. I recall OLM's in mid-2000's Chrysler products literally counting down a set number of miles. That's all the OLM appeared to be.    I would actually expect GM to be able to explain the parameters that their OLM takes into account from a high level. No, I would not expect them to disclose their software coding or data analysis around their parameters.   So we're talking about two different topics, so to continue the subject on the other one, I'd be curious to know how much "standard particulate matter" in fresh oil is able to be filtered at first start by a fresh oil filter. How much particulate matter is enough to "matter"?   I.e. how much of a "lever" do we think this equates to (variability in particulate content, in fresh oils, between different makes/brands, some which filter less, and some that filter more).   We can say that more particles = more wear = shorter engine life as a logical statement and use that data with a little marketing to scare people into selecting a more refined/filtered oil. Using a similie, is this like deciding to forego two alcoholic drinks in a lifetime because we're worried about the potential impact on lifespan? Are there numbers which translate the ISO test results into a quantifiable increase in wear for a given engine/use case?

      I'm pretty sure it doesn't actually recalibrate the speedometer it just changes the wheel speed sensor inputs to the computer. The truck still thinks it has stock tires.
